恋上你是我今生的福爱上你是我今生的缘
[liàn shàng nĭ shì wŏ jīn shēng de fú ài shàng nĭ shì wŏ jīn shēng de yuán]
This means 'Falling in love with you is my blessing; loving you is my destined relationship in this life.' It shows deep gratitude and belief in the importance and predestined nature of one's feelings for someone else.
